Some friends and I are going to start the climb to floor 200 tonight and basically I was curious how daunting of a task this is? We'll be a party of 4 with healer (SCH), tank (DRK or WAR), and 2 dd(NIN or SMN, BLM or MCH). Would this be a good comp or are we better off doing something different? Our weapons/armor are all around 70. Also how would you compare the difficulty of the last 20 or so floors?
